1.12.0

  • Added support for parsing Wasm frames of Chrome (V8), Firefox, Safari.
  • Require Dart 3.4 or greater

1.11.1

  • Make use of @pragma('vm:awaiter-link') to make package work better with Dart VM's builtin awaiter stack unwinding. No other changes.

1.11.0

  • Added the parameter zoneValues to Chain.capture to be able to use custom zone values with the runZoned internal calls.
  • Populate the pubspec repository field.
  • Require Dart 2.18 or greater

1.10.0

  • Stable release for null safety.
  • Fix broken test, test/chain/vm_test.dart, which incorrectly handles asynchronous suspension gap markers at the end of stack traces.

1.10.0-nullsafety.6

  • Fix bug parsing asynchronous suspension gap markers at the end of stack traces, when parsing with Trace.parse and Chain.parse.
  • Update SDK constraints to >=2.12.0-0 <3.0.0 based on beta release guidelines.

1.10.0-nullsafety.5

  • Allow prerelease versions of the 2.12 sdk.

1.10.0-nullsafety.4

  • Allow the 2.10.0 stable and dev SDKs.

1.10.0-nullsafety.3

  • Fix bug parsing asynchronous suspension gap markers at the end of stack traces.

1.10.0-nullsafety.2

  • Forward fix for a change in SDK type promotion behavior.

1.10.0-nullsafety.1

  • Allow 2.10 stable and 2.11.0 dev SDK versions.

1.10.0-nullsafety

  • Opt in to null safety.

1.9.6 (backpublish)

  • Fix bug parsing asynchronous suspension gap markers at the end of stack traces. (Also fixed separately in 1.10.0-nullsafety.3)
  • Fix bug parsing asynchronous suspension gap markers at the end of stack traces, when parsing with Trace.parse and Chain.parse. (Also fixed separately in 1.10.0-nullsafety.6)

1.9.5

  • Parse the format for data: URIs that the Dart VM has used since 2.2.0.

1.9.4

  • Add support for firefox anonymous stack traces.
  • Add support for chrome eval stack traces without a column.
  • Change the argument type to Chain.capture from Function(dynamic, Chain) to Function(Object, Chain). Existing functions which take dynamic are still fine, but new uses can have a safer type.

1.9.3

  • Set max SDK version to <3.0.0.

1.9.2

  • Fix Dart 2.0 runtime cast failure in test.

1.9.1

  • Preserve the original chain for a trace to handle cases where an error is rethrown.

1.9.0

  • Add an errorZone parameter to Chain.capture() that makes it avoid creating an error zone.

1.8.3

  • Chain.forTrace() now returns a full stack chain for all StackTraces within Chain.capture(), even those that haven't been processed by dart:async yet.

  • Chain.forTrace() now uses the Dart VM's stack chain information when called synchronously within Chain.capture(). This matches the existing behavior outside Chain.capture().

  • Chain.forTrace() now trims the VM's stack chains for the innermost stack trace within Chain.capture() (unless it's called synchronously, as above). This avoids duplicated frames and makes the format of the innermost traces consistent with the other traces in the chain.

1.8.2

  • Update to use strong-mode clean Zone API.

1.8.1

  • Use official generic function syntax.

  • Updated minimum SDK to 1.23.0.

1.8.0

  • Add a Trace.original field to provide access to the original StackTraces from which the Trace was created, and a matching constructor parameter to new Trace().

1.7.4

  • Always run onError callbacks for Chain.capture() in the parent zone.

1.7.3

  • Fix broken links in the README.

1.7.2

  • Trace.foldFrames() and Chain.foldFrames() now remove the outermost folded frame. This matches the behavior of .terse with core frames.

  • Fix bug parsing a friendly frame with spaces in the member name.

  • Fix bug parsing a friendly frame where the location is a data url.

1.7.1

  • Make Trace.parse(), Chain.parse(), treat the VM's new causal asynchronous stack traces as chains. Outside of a Chain.capture() block, new Chain.current() will return a stack chain constructed from the asynchronous stack traces.

1.7.0

  • Add a Chain.disable() function that disables stack-chain tracking.

  • Fix a bug where Chain.capture(..., when: false) would throw if an error was emitted without a stack trace.

1.6.8

  • Add a note to the documentation of Chain.terse and Trace.terse.

1.6.7

  • Fix a bug where new Frame.caller() returned the wrong depth of frame on Dartium.

1.6.6

  • new Trace.current() and new Chain.current() now skip an extra frame when run in a JS context. This makes their return values match the VM context.

1.6.5

  • Really fix strong mode warnings.

1.6.4

  • Fix a syntax error introduced in 1.6.3.

1.6.3

  • Make Chain.capture() generic. Its signature is now T Chain.capture<T>(T callback(), ...).

1.6.2

  • Fix all strong mode warnings.

1.6.1

  • Use StackTrace.current in Dart SDK 1.14 to get the current stack trace.

1.6.0

  • Add a when parameter to Chain.capture(). This allows capturing to be easily enabled and disabled based on whether the application is running in debug/development mode or not.

  • Deprecate the ChainHandler typedef. This didn't provide any value over directly annotating the function argument, and it made the documentation less clear.

1.5.1

  • Fix a crash in Chain.foldFrames() and Chain.terse when one of the chain's traces has no frames.

1.5.0

  • new Chain.parse() now parses all the stack trace formats supported by new Trace.parse(). Formats other than that emitted by Chain.toString() will produce single-element chains.

  • new Trace.parse() now parses the output of Chain.toString(). It produces the same result as Chain.parse().toTrace().

1.4.2

  • Improve the display of data: URIs in stack traces.

1.4.1

  • Fix a crashing bug in UnparsedFrame.toString().

1.4.0

  • new Trace.parse() and related constructors will no longer throw an exception if they encounter an unparseable stack frame. Instead, they will generate an UnparsedFrame, which exposes no metadata but preserves the frame's original text.

  • Properly parse native-code V8 frames.

1.3.5

  • Properly shorten library names for pathnames of folded frames on Windows.

1.3.4

  • No longer say that stack chains aren't supported on dart2js now that sdk#15171 is fixed. Note that this fix only applies to Dart 1.12.

1.3.3

  • When a null stack trace is passed to a completer or stream controller in nested Chain.capture() blocks, substitute the inner block's chain rather than the outer block's.

  • Add support for empty chains and chains of empty traces to Chain.parse().

  • Don't crash when parsing stack traces from Dart VM stack overflows.

1.3.2

  • Don't crash when running Trace.terse on empty stack traces.

1.3.1

  • Support more types of JavaScriptCore stack frames.

1.3.0

  • Support stack traces generated by JavaScriptCore. They can be explicitly parsed via new Trace.parseJSCore and new Frame.parseJSCore.

1.2.4

  • Fix a type annotation in LazyTrace.

1.2.3

  • Fix a crash in Chain.parse.

1.2.2

  • Don't print the first folded frame of terse stack traces. This frame is always just an internal isolate message handler anyway. This improves the readability of stack traces, especially in stack chains.

  • Remove the line numbers and specific files in all terse folded frames, not just those from core libraries.

  • Make padding consistent across all stack traces for Chain.toString().

1.2.1

  • Add terse to LazyTrace.foldFrames().

  • Further improve stack chains when using the VM's async/await implementation.

1.2.0

  • Add a terse argument to Trace.foldFrames() and Chain.foldFrames(). This allows them to inherit the behavior of Trace.terse and Chain.terse without having to duplicate the logic.

1.1.3

  • Produce nicer-looking stack chains when using the VM's async/await implementation.

1.1.2

  • Support VM frames without line or column numbers, which async/await programs occasionally generate.

  • Replace <<anonymous closure>_async_body> in VM frames' members with the terser <async>.

1.1.1

  • Widen the SDK constraint to include 1.7.0-dev.4.0.

1.1.0

  • Unify the parsing of Safari and Firefox stack traces. This fixes an error in Firefox trace parsing.

  • Deprecate Trace.parseSafari6_0, Trace.parseSafari6_1, Frame.parseSafari6_0, and Frame.parseSafari6_1.

  • Add Frame.parseSafari.

1.0.3

  • Use Zone.errorCallback to attach stack chains to all errors without the need for Chain.track, which is now deprecated.

1.0.2

1.0.1

  • Synchronous errors in the [Chain.capture] callback are now handled correctly.

1.0.0

  • No API changes, just declared stable.

0.9.3+2

  • Update the dependency on path.

  • Improve the formatting of library URIs in stack traces.

0.9.3+1

  • If an error is thrown in Chain.capture's onError handler, that error is handled by the parent zone. This matches the behavior of runZoned in dart:async.

0.9.3

  • Add a Chain.foldFrames method that parallels Trace.foldFrames.

  • Record anonymous method frames in IE10 as "".
